Same as it's possible to hate a movie based on the first eight minutes.
And no, my opinion will not change until IMDB rescinds its classification of "Eternal Sunshine of the Spotless Mind" as "science fiction".
If they do that, I will merely have no opinion, instead of loathing it entirely. Because when a movie where the first eight minutes consists of Jim Carrey walking around being emo with a bunch of artsy camera angles displaces "The Matrix" for the number 3 slot in the "best sci-fi movies of all time" list, something is seriously wrong.
EDIT: Yeah, I'm quoting TLTE. Damn you people are fast.
